The reproductive system of the male agouti is not well documented. This study describes the specific anatomical features of the free part of the penis occurring during penile erection in the agouti. Electro-ejaculation was used to induce erection in three male agoutis that had previously produced offspring. Results proved that there were four stages in the erection process. Stage 1 involved protrusion of the penis from the preputial orifice. The lateral penile cartilages were then spread (stage 2). During stage 3, there was the blooming of the head of the glans penis (penile flower) and eversion of the intromittent sac. The protrusion of the keratinaceous styles and ejaculation occurred during stage 4. This information could assist in semen collection for use in reproductive techniques for the agouti such as artificial insemination.
刺豚鼠雄性生殖系统的相关记录并不完善。本研究描述了刺豚鼠阴茎勃起时阴茎游离部分的具体解剖特征。采用电刺激射精法诱导三只曾繁育过后代的雄性刺豚鼠勃起。结果证明，勃起过程有四个阶段。第一阶段，阴茎从包皮口突出。随后阴茎侧软骨展开（第二阶段）。在第三阶段，龟头（阴茎花）隆起，交配囊外翻。角质化阴茎刺突出及射精发生在第四阶段。这些信息有助于在刺豚鼠的生殖技术如人工授精中采集精液。
